Manufactured by Kaysam Industries in 1982. These balloons are military surplus and are in perfect condition as they are packaged in an air tight, sealed plastic bag. Each balloon weighs about 5 pounds. This balloon CAN be inflated to 10 to 12 foot in diameter, however they start to look pretty good at about 5 foot in diameter and will fly nicely at about 7 foot in diameter. How much can this balloon lift? The balloon in the night picture was inflated with Hydrogen to about 7-1/2 feet in diameter and it had almost 7 pounds of lift. It was getting hard to hold onto after while, it wanted to fly! Recommended links: http://www.thefintels.com/aer/hab1.htm (First flight) http://www.thefintels.com/aer/hab2.htm (second flight) http://www.howstuffworks.com/helium2.htm (information about helium balloons) http://picasaweb.google.com/blossomlandara/Aug2008Balloon?feat=directlink# (another group's flight) These balloons vary a little in weight averaging 2277 grams or 5 pounds each. THE BALLOON SHIPPED TO YOU MAY WEIGH A LITTLE MORE OR LESS THAN THAT. These balloons are great fun. Inflate one of these in your boss's office on his birthday, that would get everyone a raise! Great for events, (such as a balloon festival,) and promotions. They can be used as a means for ariel photography. Experiments using a balloon like this will not be forgotten. The math needed to figure the volume of cubic feet in this balloon at various diameters as well as the lifting capacity of Helium and Hydrogen are only a few of the reasons these balloons are so interesting. Please email me your experiences. Buyer should be aware that these balloons are delicate (not because they are old but because of their nature being made of thin latex rubber) and need to be handled with care! Tree branches will pop them. Sharp stuff on the grass will pop them. Compressor hoses stuck inside them can pop them. You need at least two people to handle the balloon while you're inflating it, one to hold the air/gas supply hose and one to support the balloon while it fills. Regular air compressors will inflate this balloon but that would be my last choice because you need lots of air volume at low pressure, just the opposite of what most air compressors deliver (and you don't want to hold up a 5 pound balloon up for an hour while it fills, your arms will fall off!) A yard leaf blower adapted down to about a 3/4" PVC pipe (duct tape, and sand the end edges smooth) will work great. If you are careful you can probably reuse the balloon, however they are designed for one use. Information from a customer.......... For your information I discovered that it takes an entire tank of helium to fill one balloon giving it 7.5lbs of lift (with the rubber skirt on the bottom carefully removed). Thanks Justin! Note: This customer was looking for lifting capacity using 100% helium. You can use helium to achieve lift off plus a few pounds of lift and then finish filling the balloon with regular air. Doing this will put your balloon, fully inflated, in the air for less money. You don't have to fill these balloons with helium to have a lot of fun. My neighbor called the cops when he saw the balloon on the light pole (the one pictured.) (PLEASE DON'T HANG A BALLOON FROM ELECTRICAL WIRES.) He thought it was from the Air Force Test Range in Utah's western desert. Ebay price $25 Each: The last time the government purchased these balloons in 1991 they paid $191.00 EACH for a quanity of over 5000 balloons. I don't offer this balloon at any better price in ANY quantity, just in case you're thinking of asking me like many folks have done (however, I can save you some money on the shipping.) SHIPPING IN THE CONTINENTAL U. S.: Buyer pays $15.00 shipping on ANY quantity in the continental United States. AK & HI: Ebay's new shipping price rules don't allow for all the scenarios like Alaska and Hawaii, I'll send you an invoice if you purchase more than two balloons otherwise it's $15.00. INTERNATIONAL SHIPPING: Buyer pays USPS Priority shipping cost plus $5.00 handling. The U.S. Postal Service has discontinued Surface shipping so USPS Priority (6 to 10 days) shipping is probably going to cost you more than the cost of the balloon, it it's the least expensive option. PAYMENT: Paypal or other Please check out my other interesting items! Thanks for looking and buying! Dale PTL More details: The balloons fill from the top... since the skirt is on the bottom. A stopper ball with a heavy string attached to it lodges in the neck of the balloon. That string is what I used to hang my balloon from the pole in the photo. Another throat/stopper is at the bottom of the skirt except it's not used for filling the skirt as the skirt has a couple holes in it to self adjust to size and pressure. The stopper string coming out of the skirt can be used to attach stuff to if you let it go. For anchoring the balloon, there is a heavier collar, (about 3" diameter,) right above the throat/stopper that you could attach an anchor line to with some tough tape.
